Using Traps for Pest Management

A proactive midyear scouting plan is critical when managing insect risks. Trapping is one strategy used to predict an insect invasion. In Episode 6 of Corn College TV Season 3, Farm Journal’s Field Agronomist Ken Ferrie describes how to properly set a trap.

Setting a trap is an inexpensive way to track common insects. Ferrie says that western bean cutworms and European corn borers are the most common Midwestern midseason pests to be looking out for.

To make a trap, cut out a hole in a milk jug and make a soapy water mixture that will sit in the bottom of the jug. Put pheromone in the lid as a lure for whichever insect that is being tested for. The male moths will be attracted to the female pheromone and will be trapped by the soapy water.

Ferrie says, "When this thing starts loading up with moths, you know you have heavy flight, they’re out here mating, and they’re going to be laying eggs." Set up a trap line with neighbors so that the insects can be tested for throughout the area. This system could help predict between 3-10 days before insecticide is needed.
